Earl's Speed-Seal hose ends are reusable and have a proven record of reliability throughout the racing industry. Because brake system hose ends are subject to wear and tear from extreme vibration, these forged hose ends have an 80 percent greater wall thickness than any other on the market. These Speed-Seal hose ends are available in stainless steel or aluminum, bent tube or low-profile, and adjustable or non-adjustable configurations. They're made for use with Speed-Flex smooth bore hoses.
